Subject: [PATCH 1/2] staging: rtl8723bs: Simplify underutilized 2D array to
1D array
Member variable "Value" of structure iqk_matrix_regs_setting is
declared to be a 2D array of [3][IQK_Matrix_REG_NUM] grid. However
the primary index of this array is only used for index 0, the other
two elements are never used. Simplify this array to a one dimension
degree. The resultant code is simpler and is easy to maintain.
